Answer:
Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.
Answer:
When clotting factors in the plasma are activated to form a blood clot, the fluid portion of plasma that remains is known as <u>serum.</u>
Explanation:
The liquid part of blood is known as the plasma. it makes about 90 per cent of the blood and comprises of antibodies and the clotting factors.
If the clotting factors or the fibrinogens are removed from the plasma, then the fluid that remains is termed as serum. The blood serum contains useful proteins like the albumin and antibodies. The serum is the part of the blood that is mostly used for the diagnostic tests.
A population of frogs with
slightly different coloring is an example of microevolution. Microevolution is
the changes in the gene pool of a population that can be measured and observed in
short periods of time within a population. Microevolution can take place in
several ways such as gene flow, genetic drift, mutation and selection.
The earth is surrounded by <em>a layer of</em> gases called the <em>atmosphere</em>. The atmosphere is very <em>important </em>to life on <em>Earth</em> and does many <em>things</em> to help protect life and help<em> life </em>to survive.
The atmosphere absorbs the <em>heat</em> from the <em>Sun </em>and keeps the heat <em>inside</em> the atmosphere helping the <em>Earth </em>to stay warm, called the <em>Greenhouse </em>Effect.
Answer:
The correct answer is included in the Explanation section
Explanation:
An organism with considerable more chromosomes than humans: the plant <em>Ophioglossum reticulatum</em> with 1260 chromosomes.
An organism with considerable fewer chromosomes than humans: the ant <em>Myrmecia pilosula</em> with 1 chromosome.
It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.
